some type cleanup work

MFZE1

Fix call_user_function

- make class tables contain class_entry *, not class_entry
- fix isset($this)

- Remove use of C++ reserved words namespace/this

break custom objects like COM, Java, etc. - this will be fixed later.

- them and what kind of logic you're allowed to do inside of them.
